Grate the chicken with spices, salt and garlic passed through a press, pour the lemon juice on top. You can put the halves of the lemon inside with rosemary or use only rosemary if you are afraid that the lemon will give a lot of acid. Tie the chicken legs together.
Peel the potatoes and cut them into small cubes. Salt, pepper and pour the oil, mix well and put the potatoes along with the chicken on a baking sheet.
Pour meat broth and wine into the mold; the broth can be replaced with water. Bake at 200 degrees 40 minutes.
